BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a technique for supporting the user of a game apparatus.

2. Description of the Related Art

Portable game terminals have become broadly popular, which allow a user to enjoy a game with ease even if the user is away from home. An increasing number of users enjoy a game when they have a few minutes of spare time, in a period of time when they are on the move, such as being on a train, or when they are waiting to meet someone. In addition, portable game terminals have become available which have a function of establishing a connection to the Internet via access points installed in urban areas and the like. Such portable game terminals allow the user to enjoy a new game after it is downloaded even if the user is away from home.

There is a demand for a service which is configured such that, before the user downloads a new game, it predicts the user's preferences based upon the user action history, and to recommend a game suitable for the user, which is convenient. As a technique for acquiring and analyzing log information which specifies the user action history, Patent document 1 is known, for example.

However, when the user desires to take on a new game in the user's spare time, there is no information with respect to the time required for the game. Accordingly, a prediction cannot be made beforehand of whether or not the user can finish the game in the user's spare time. If the user cannot finish the game in the user's spare time, the user must suspend the game before the user finishes the game, or otherwise the user must save the game in an unsatisfactory state. That is to say, although the user initiates a game, such a game has the potential to waste the user's spare time. Accordingly, in many cases, even if the user has spare time, the user selects one from among a limited number of games with respect to which the user can estimate the time required to finish the game, i.e., games which have already been played. That is to say, this leads to the user losing the chance to take on a new game.

SUMMARY OF THE INVENTION

Accordingly, it is a general purpose of the present invention to provide a technique for supporting game device users, and for providing improved user convenience.

In order to solve the aforementioned problem, a game support server according to the present embodiment comprises: a skill level acquisition unit configured to acquire, from a first game apparatus, a skill level that indicates a user's degree of skill in a game; a game database configured to store a standard time required to play a game; a recommendation request receiving unit configured to acquire, from a second game apparatus, a desired time period that the user wishes to spend playing a game, and to receive a request to recommend at least one candidate game that matches the desired time; a recommended candidate extraction unit configured to modify the standard time according to a user's skill level acquired by the skill level acquisition unit so as to calculate an estimated time that is an estimate of time to be required for the user to play a game, and to extract, as a recommended candidate game from the game database, a game if the difference between the estimated time and the desired time is less than or equal to a predetermined value; and a recommended candidate presenting unit configured to present to the second game apparatus the recommended candidate game thus extracted by the recommended candidate extraction unit.

A game apparatus according to another embodiment of the present invention comprises: a recommendation request transmitting unit configured to acquire a desired time that the user wishes to spend playing a game, and to request that a game support server recommend games matching the desired time; a recommended candidate acquisition unit configured to acquire, from the game support server, at least one recommended candidate game if the difference between the desired time and an estimated time, which is an estimate of time required for a user to play the game calculated by modifying a standard time required for game play according to a skill level indicating the user's degree of skill in the game, is less than or equal to a predetermined value; and a recommended candidate display unit configured to display the recommended candidate game acquired by the recommended candidate acquisition unit.

It should be noted that any combination of the aforementioned components or any manifestation of the present invention may be mutually substituted between a method, apparatus, system, recording medium, computer program, and so forth, which are effective as an embodiment of the present invention.

[Functional Configuration of Game Support Server 100]

FIG. 8 shows a functional configuration of the game support server 100. The game support server 100 includes a control unit 180, a game database 192, a user database 193, and a game program holding unit 194. The control unit 180 includes a user registration unit 181, a skill level acquisition unit 182, an authentication unit 183, a recommendation request receiving unit 184, a recommended candidate extraction unit 185, a recommended candidate presenting unit 186, a download control unit 187, a play history acquisition unit 188, a skill level calculation unit 189, a play time calculation unit 190, and a history transmitting unit 191. Such functional blocks can also be realized by hardware components alone, software components alone, or various combinations thereof.

FIG. 9 shows an example of an internal data structure of the game database 192. The game database 192 includes a game ID field 130, a title field 131, a category field 132, and a standard play time field 133. The game ID field 130 stores IDs for game identification. The title field 131 stores the title of each game. The category field 132 stores a category to which each game belongs. Examples of categories include “table game”, “quiz game”, “puzzle game”, and so forth. The standard play time field 133 stores the standard play time required for each game. At the time point at which the game support server 100 starts to supply the service, the standard play time field 133 stores the average play time obtained based upon game execution results provided by tester players or the like. Subsequently, the standard play time is updated by the play time calculation unit 190 with reference to the user play history acquired by the play history acquisition unit 188, as described later.

FIG. 10 shows an example of an internal data structure of the user database 193. The user database 193 includes a user ID field 140, a user name field 141, a password field 142, a portable information terminal device ID field 143, a game apparatus device ID field 144, a favorite field 145, and a skill level field 146. The user ID field 140 stores IDs for user identification. The user name field 141 stores the user names. The password field 142 stores passwords set by respective users for authentication. The portable information terminal device ID field 143 stores the device IDs of the respective portable information terminals 10 to be used by the respective users. The game apparatus device ID field 144 stored the device IDs of the respective game apparatuses 200 to be used by the respective users. With such an arrangement, the user can log in to the game support server 100 using the same user ID regardless of whether the device via which the user logs in is the portable information terminal 10 or the game apparatus 200. Furthermore, such an arrangement is capable of judging based upon the device ID whether the device via which the user log in is the portable information terminal 10 or the game apparatus 200. The favorite field 145 stores the user's preferred game categories. The skill level field 146 stores the user's skill level for each category. At the time point at which the user is registered, the skill level field 146 stores the user's self-reported skill level. The skill level is updated by the skill level calculation unit 189 with reference to the user's play history acquired by the play history acquisition unit 188, as described later.

The user registration unit 181 is configured to receive a user registration request from the portable information terminal 10 or otherwise the game apparatus 200, and to register, in the user database 193, the information with respect to the user received from the portable information terminal 10 or otherwise the game apparatus 200. When the user registration unit 181 accepts a user registration request, the skill level acquisition unit 182 is configured to acquire the skill level of the user from the portable information terminal 10 or otherwise the game apparatus 200, and to register the user's skill level thus acquired in the user database 193.

Before the user of the portable information terminal 10 receives service from the game support server 100, the authentication unit 183 is configured to receive the user's authentication information from the portable information terminal 10, and to authenticate the user with reference to the user database 193. The authentication unit 183 is configured to transmit the authentication result to the portable information terminal 10. When the authentication succeeds, the game support server 100 supplies service to the portable information terminal 10 of the user. Conversely, when the authentication fails, the game support server 100 supplies no service to the portable information terminal 10 of the user.

The recommendation request receiving unit 184 is configured to receive a recommendation request for games that match the user's desired play time. The recommendation request receiving unit 184 is configured to acquire the user's desired play time from the portable information terminal 10, and to notify the recommended candidate extraction unit 185 of this information. The recommended candidate extraction unit 185 is configured to extract the game candidates that match the user's desired play time, giving consideration to the user's skill level with reference to the game database 192 and the user database 193.

After the recommendation request receiving unit 184 receives a recommendation request from the user via the portable information terminal 10, first, the recommended candidate extraction unit 185 reads out the skill level of this user for each category from the user database 193. Subsequently, the recommended candidate extraction unit 185 corrects the standard play time stored in the game database 192 for each game based upon the user's skill level, so as to calculate the estimated user's play time. For example, such an arrangement calculates the estimated play time by multiplying the standard play time by a correction coefficient configured such that it is raised from 1 as the user's skill level becomes lower than the average skill level, and such that it is reduced from 1 as the user's skill level becomes higher than the average skill level. Thus, as the user's skill level becomes higher than the average, the estimated play time thus calculated becomes shorter than the standard play time. Conversely, as the user's skill level becomes lower than the average, the estimated play time thus calculated becomes longer than the standard play time. The correction coefficient may be set for each game, or for each game category. For example, in a case in which the game is a role-playing game or a puzzle game, it is likely that the play time varies widely according to the user's skill level. Accordingly, in this case, the contribution of the correction coefficient may be increased. In contrast, in a case in which the game is a quiz game configured to provide a predetermined number of questions, or to provide a fixed solving time, it is likely that the play time varies little regardless of the skill of the user. Thus, in this case, the contribution of the correction coefficient may be reduced.

The correction coefficient may be calculated using a calculation expression including statistics such as the average value, the standard deviation, the median, etc. The recommended candidate extraction unit 185 is configured to extract, as the recommended game candidates, the games for which the estimated play time is almost the same as the user's desired play time. Also, the recommended candidate extraction unit 185 may extract, as the recommended game candidates, the games for which the difference between the estimated play time and the desired play time is equal to or smaller than a predetermined value. Also, the recommended candidate extraction unit 185 may extract, as the recommended game candidates, the games for which the difference between the estimated play time and the desired play time is equal to or smaller than a predetermined value, and the estimated play time is shorter than the user's desired play time. Also, the recommended candidate extraction unit 185 may extract, as the recommended game candidates, a combination of multiple games for which the difference between the user's desired play time and the sum total of the estimated play times for the multiple games is equal to or smaller than a predetermined value. Also, the recommended candidate extraction unit 185 may be configured to extract the recommended game candidates with reference to the user preference information or the attribute information such as the user's favorite game category information.

The recommended candidate presenting unit 186 is configured to present the recommended game candidates thus extracted by the recommended candidate extraction unit 185 to the portable information terminal 10. In this stage, the recommended candidate presenting unit 186 may present the recommended game candidates sorted such that games in the user's favorite category are listed at the top. Also, the recommended candidate presenting unit 186 may display games in the user's favorite category in a highlighted manner. The download control unit 187 is configured to receive a game program download request from the portable information terminal 10, to read out the requested game program from the game program holding unit 194, and to transmit the game program thus read out to the portable information terminal 10.

The play history acquisition unit 188 is configured to acquire, from the portable information terminal 10 or otherwise the game apparatus 200, the information with respect to the history of games executed by the user. The skill level calculation unit 189 is configured to calculate the user's skill level with reference to the game execution history acquired by the play history acquisition unit 188, and to update the user database 193. The play time calculation unit 190 is configured to calculate the standard play time for the game with reference to the game execution history acquired by the play history acquisition unit 188, and to update the game database 192.

The skill level calculation unit 189 may raise the user's skill level for the category to which a game belongs, according to the number of times the user has played the game, or the play time which the user has spent on the game. For example, the skill level calculation unit 189 may raise, by a predetermined value, the skill level for the category to which a game belongs every time the user plays the game. Also, when the play time which the user has spent executing a game is equal to or greater than a predetermined value, the skill level calculation unit 189 may raise, by a predetermined value, the skill level for the category to which the game belongs. In such a case, the aforementioned predetermined value by which the skill level is to be raised may be increased according to an increase in time which the user has spent playing the game. Also, as the difficulty level of the game which the user has played becomes higher, the aforementioned predetermined value by which the skill level is to be raised may be increased. In this case, the game database 192 is configured to store the game difficulty level.

The skill level calculation unit 189 is configured to make a comparison between the actual play time which the user has spent playing a game and the standard play time set for the game. When the user's play time is longer than the standard play time, the skill level calculation unit 189 may reduce the user's skill level. Conversely, when the user's play time is shorter than the standard play time, the skill level calculation unit 189 may increase the user's skill level. Also, a predetermined value, which is to be added to or subtracted from the user's skill level, may be increased according to an increase in difference between the user's play time and the standard play time.

Based upon the game score of a game which the user has played, when the user's game score is higher than the standard game score, the skill level calculation unit 189 may raise the user's skill level. Conversely, when the user's game score is lower than the standard game score, the skill level calculation unit 189 may reduce the user's skill level. Also, a predetermined value, which is to be added to or subtracted from the user's skill level, may be increased according to an increase in difference between the user's game score and the standard score. In this case, the game database 192 is configured to store the standard score for each game. At the time point at which the service starts to be supplied, the game database 192 may store the average score obtained based upon game score results provided by tester players or the like, as with the standard play time. Subsequently, the standard score may be updated for each user with reference to the game play history.

The skill level calculation unit 189 may be configured to calculate the skill level using a method obtained by combining the aforementioned methods. A predetermined value by which the skill level is to be raised or reduced by the skill level calculation unit 189 may be changed for every category.

The play time calculation unit 190 may use the average of the actual play time acquired from users as the standard play time. Also, the play time calculation unit 190 may use, as the standard play time, the weighted average obtained by averaging the actual play time weighted by the aforementioned correction coefficient. Also, the average of values obtained by dividing the actual play time by a correction coefficient that corresponds to the user's skill level may be used as the standard play time.

[Procedure of Game Support Method]

FIG. 11 is a sequence diagram which shows the procedure of a game support method according to the present embodiment. In FIG. 11 and the subsequent drawings, each step of each operation will be indicated by a combination of “S” (which is the initial letter of “Step”) which represents “Step” and a number. First, the user makes a request for user registration to the game support server 100 via the portable information terminal 10 or otherwise the game apparatus 200. Description will be made below regarding an example in which the portable information terminal 10 requests the game support server 100 for user registration. The user registration request unit 81 included in the portable information terminal 10 transmits, to the game support server 100, the authentication information such as the user name, password, etc., and the user's attribute or preference information such as the user's favorite game category information etc. (S110). The skill level transmitting unit 82 included in the portable information terminal 10 transmits the user's skill level to the game support server 100 (S112). The user registration unit 181 included in the game support server 100 registers, in the user database 193, the user information received from the portable information terminal 10, and the skill level acquisition unit 182 registers the user's skill level in the user database 193 (S114).

Before the user receives the recommended game candidates from the game support server 100 when the user desires to play a game in the user's spare time and the like, first, the user logs in to the game support server 100. The login processing unit 83 included in the portable information terminal 10 transmits the user authentication information to the game support server 100 (S120). The authentication unit 183 included in the game support server 100 authenticates the user based upon the authentication information thus received, with reference to the user database 193 (S122), and transmits the authentication result to the portable information terminal 10 (S124). When the authentication fails, the user cannot receive the service from the game support server 100. Description will be made below assuming that the authentication succeeds.

When the recommendation request transmitting unit 84 included in the portable information terminal 10 transmits the user's desired play time to the game support server 100 (S130), the recommendation request receiving unit 184 included in the game support server 100 acquires the user's skill level from the user database 193 (S132), and notifies the recommended candidate extraction unit 185 of this information. The recommended candidate extraction unit 185 extracts, from the game database 192, the recommended game candidates which match the user's desired play time, based upon the user's skill level (S134). The recommended candidate presenting unit 186 presents the recommended game candidates to the portable information terminal 10 (S136). The game candidates recommended by the game support server 100 are displayed on the display 23 by the recommended candidate display unit 86 included in the portable information terminal 10.

When the user selects a desired game to be played from among the recommended game candidates, the download request unit 87 included in the portable information terminal 10 requests the game support server 100 to download the game program thus selected (S140). The download control unit 187 included in the game support server 100 reads out the game program thus requested from the game program holding unit 194, and transmits the game program thus read out to the portable information terminal 10 (S142). The game program acquisition unit 88 included in the portable information terminal 10 instructs the game program holding unit 93 to store the game program thus acquired.

FIG. 12 shows an example of a screen displayed on the display 23 by the recommended candidate display unit 86 of the portable information terminal 10. Such an arrangement displays on the screen only a list of the game candidates with respect to which it is predicted that the user can finish the game in 15 minutes, which matches the user's desired play time. When a game program is not held by the game program holding unit 93, the recommended candidate display unit 86 displays a download button 98 for the game. Conversely, when a game program is held by the game program holding unit 93, the recommended candidate display unit 86 displays an execution button 99 for the game. When the user clicks the download button 98, the download request unit 87 requests the game support server 100 to download the corresponding game program. When the user clicks the execution button 99, the game executing unit 89 reads out the game program from the game program holding unit 93, and executes the game program thus read out. When a game belongs to a category set as the user's favorite, the recommended candidate display unit 86 displays a mark 97 for the game. The recommended candidate display unit 86 may display the game candidates in ascending order of the difference between the estimated play time and the user's desired play time. Also, the recommended candidate display unit 86 may display the game candidates in descending order of, or otherwise in ascending order of, the estimated play time. Also, the recommended candidate display unit 86 may display the game candidates in an order sorted based upon the user's attribute information or preference information.

FIG. 13 is a sequence diagram which shows a procedure for updating the standard play time and the user's skill level in the game support method according to the present embodiment. The user plays a game using the portable information terminal 10 or otherwise the game apparatus 200. Description will be made below regarding an example in which the user plays a game using the portable information terminal 10. When the game executing unit 89 included in the portable information terminal 10 executes a game program (S150), the history recording unit 90 records the play history in the history holding unit 92 (S152). The history transmitting unit 91 included in the portable information terminal 10 reads out the play history from the history holding unit 92 at a predetermined timing, and transmits the play history thus read out to the game support server (S160). The play time calculation unit 190 included in the game support server 100 calculates the standard play time for the game at a predetermined timing with reference to the play history acquired from the portable information terminal 10, and updates the standard play time field 133 in the game database 192 (S170). The skill level calculation unit 189 included in the game support server 100 calculates the user's skill level at a predetermined timing with reference to the play history acquired from the portable information terminal 10, and updates the skill level field 146 in the user database 193 (S172).

The present embodiment is capable of recommending game candidates extracted with high precision such that they fit into the user's spare time when the user desires to play a game in the user's spare time or the like.

Second Embodiment

Description will be made in the second embodiment regarding an example in which the game apparatus 200 is shared by multiple users. In a case in which the multiple users who share the game apparatus 200 each log in to the game support server 100 using their own user IDs, the same technique as in the first embodiment can be applied. However, in a case in which the multiple users who share the game apparatus 200 each log in to the game support server 100 using a single user ID, the multiple users having different respective skill levels share the same user ID. Accordingly, with the present embodiment, the user's own skill level is transmitted to the game support server 100 every time the user requests the game support server 100 to recommend a game.

There are differences in the external configuration and the circuit configuration between the game apparatus 200 and the portable information terminal 10. However, the game apparatus 200 has the same basic circuit configuration as that of the portable information terminal 10. Furthermore, the functional configuration for providing the game support method according to the present invention is the same as that of the portable information terminal 10 according to the first embodiment.

FIG. 14 is a sequence diagram which shows the procedure for providing the game support method according to the present embodiment. Description will be made regarding the point of difference from the game support method according to the first embodiment shown in FIG. 11. In the present embodiment, Step S112 in which the user's skill level is transmitted to the game support server 100 when the user is registered is omitted. Instead, when the recommendation request transmitting unit 84 included in the game apparatus 200 requests the game support server 100 to recommend the game candidates, the skill level transmitting unit 82 transmits the user's skill level to the game support server 100 (S126). The other steps are the same as those in the first embodiment.

With the present embodiment, the user database 193 included in the game support server 100 is not required to include the skill level field 146. Furthermore, the game support server 100 is not required to include the skill level calculation unit 189.

The present embodiment is capable of recommending game candidates extracted with high precision such that they match the user conditions for each user even if a single user ID is shared by multiple users.

Third Embodiment

With the third embodiment, such an arrangement is not configured to receive the user's skill level from the user. Instead, the skill level acquisition unit 182 included in the game support server 100 calculates the user's skill level with reference to the user's play history acquired from the portable information terminal 10 or otherwise the game apparatus 200.

FIG. 15 is a sequence diagram which shows a procedure for providing a game support method according to the present embodiment. Description will be made regarding the point of difference from the game support method according to the first embodiment shown in FIG. 11. With the present embodiment, Step S112 in which the user's skill level is transmitted to the game support server 100 when the user is registered is omitted. Instead, when the recommendation request transmitting unit 84 included in the portable information terminal 10 or otherwise the game apparatus 200 requests the game support server 100 to recommend the game candidates, the skill level acquisition unit 182 included in the game support server 100 calculates the user's skill level (S133). When the skill level acquisition unit 182 has acquired the play history from the user, the skill level acquisition unit 182 reads out the play history from an unshown history holding unit, and calculates the skill level based upon the play history thus read out. When the skill level acquisition unit 182 has not acquired the play history from the user, the skill level acquisition unit 182 requests the portable information terminal 10 or otherwise the game apparatus 200 to perform transmission of the user's play history, and calculates the skill level with reference to the play history thus acquired. The skill level acquisition unit 182 may calculate the skill level using the same method as with the skill level calculation unit 189 described above in the first embodiment.

With the present embodiment, either the portable information terminal 10 or the game apparatus 200 is not required to include the skill level transmitting unit 82.

The present embodiment is capable of appropriately calculating the user's skill level, and recommending game candidates extracted with high precision such that they match the user's conditions without imposing on the user the need for self-reporting of the user's skill.

While description has been made regarding the present invention with reference to the embodiment, such description is for illustrative purposes only, and it is to be understood by those skilled in this art that changes and variations may be made without departing from the spirit or scope of the appended claims.

Description has been made in the embodiments regarding an arrangement in which the game support server 100 includes the skill level calculation unit 189.
